TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 258,520, dated May 23,1882.

Application filed March 30,1882. (ModeL) To all trhom it may concern:

Be it known that we, CLARK WooDBUaY, FOSTER W001), and ALLEN J. SAWYER,citizens of the United States, residing at Old Town, in the county ofPenobscotand State of Maine, have invented certain new and usefulImprovements in Tubular Lanterns; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawingsis a representation of a trout elevation, partlyin section, of our invention; and Fig. 2, a side elevation of the same,also partly in section, and broken away to show the manner ofswingingthe globe out.

This invention relates to that class of inventions known as tubularlanterns, and the object thereof is to provide a simple, cheap, andeasily-operated lantern that may be quickly lighted or extinguished andreadily cleaned without removing the globe, thereby rendering the saidglobe less liable to become broken whenbeing cleaned; also, should theglobe become broken when the lantern is in use the burner, beingsecurely fastened to the oil-vessel, cannot fall oft, and thereby ignitethe oil, as is often the casein lanterns of this kind. These objects weattain by the construction substantially as shown in the drawings andhereinafter described.

Inthe'accompanying drawings, A represents an oil-vessel of alantern,provided with an airchamber, B, over which is fitted the usual plate, 0,having attached thereto the burner-cap D, which is held securely inplace at all times by means of a fiat spring, a, upon the outer sideoftheair-chamber engaging with a pin, 1), upon the lower portion of theburner-cap. At the sides of the air-chamber B are connected airtubesections E F, which extend along the top of the oil-vessel and are bentup at their outer ends. To the air-tube section E is suitably hinged atube, G, and within the upper end of the air-tube section F is seatedthe lower end of a tube, H. These tubes G H communicate at their upperends with an upright tube, I, to the lower end of which is suitablyhinged the cap K of the globe L. This upright tube I is open at itslower end to admit the entrance of the air which is conveyed to theair-chamber by means of the tubes G H and air-tube sections E F. At thetop, where the nprighttubes connect with the tubes G H, is attached theusual bail for carrying or hanging the lantern.

When the lantern is intended to be lighted orextinguished itis taken inthe left hand, and a suitable latch, c, which holds the tube H in theair-tube section F, is drawn back with the right, and the weight of theoil-vessel will cause the hinge (1, connecting the tube Gr with theair-tube section E, to open, thereby dropping the burner below theglobe, as shown in dotted lines, Fig. 1, thus admitting of the lanternbeing readily lighted or extinguished without removing any of its parts.Should the lantern be resting upon a table or other support when thelatch is released with the right hand, the tubes will be drawn back withthe left to theposition also indicated by dotted lines.

The tube H, when unlatched, is prevented from lateral displacement bymeans of a flat yielding guide-plate, 6, equal in width to and workingin the bore of the said tube. This guide-plate is secured at its lowerend in the air-tube section F.

The hinge cl, beingof theconstrnctiou shown, will not allow of theoil-vessel dropping farther below the globe than is absolutely necessaryto light the wick.

YVhen the globe is to be cleaned the oil-vessel is dropped, as abovedescribed, and afastening,f, upon the globe-cap K is .turned so as toallow it to pass through a slot, g, in the plate 71. upon the lower endof the upright tube I, and thus admit of the globe-cap K, to which isattached by any suitable means the globe L, being swung out, as shown inFig. 2. By swinging the globe out, as above described, the said globemay be readily cleaned without removing the same from the lantern-frame,thus preventing the globe from becoming broken by being dropped from thehands while in the act ofcleaning, as is frequently the case where thesaid globe is entirely removed from the lantern-frame.

The burner is readily removed for the purpose of inserting a new wick byreleasing the flat spring-catch a from the pin 1) upon the burner-cap Dwhen the oil-vessel is dropped down below the globe and lit'tin g thesaid burner out from its position in the air-chamber B.

Having now fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is-- 1. Ina tubular lantern, the combination, with the tube Gr, hinged at itslower end to the stationary tube-section E, of the tube H and stationarytube-section F, the latter being provided with a fastening device forsecurely locking the tube H to the tube-section F or releasing ittherefrom, substantially as andt'or the purpose set forth.

2. lnatubnlarlantern, the combination, with the upright tube I, of thecap K, hinged thereto and carrying the globe L, substantially as and forthe purpose specified.

3. In a tubular lantern, the hinged tube G and tube H, in combinationwith the air-tube sectionsEEthelatter havinga yielding guideplate, 0,and suitable means for fastening or releasing the tube H therefrom,substantially as specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
